NATURE OF BUSINESS AND BASIS OF PRESENTATION	1. NATURE OF BUSINESS AND BASIS OF PRESENTATION Organization: The Bank of South Carolina (the “Bank”) was organized on October 22, 1986 and opened for business as a state-chartered financial institution on February 26, 1987, in Charleston, South Carolina. The Bank was reorganized into a wholly-owned subsidiary of Bank of South Carolina Corporation (the “Company”), effective April 17, 1995. At the time of the reorganization, each outstanding share of the Bank was exchanged for two shares of Bank of South Carolina Corporation Stock. Principles of Consolidation: The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, the Bank. In consolidation, all significant intercompany balances and transactions have been eliminated. References to “we”, “us”, “our”, “the Bank”, or “the Company” refer to the parent and its subsidiary that are consolidated for financial purposes. Basis of Presentation: The accompanying unaudited interim consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for the interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, our interim consolidated financial statements do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with our Annual Report on Form 10-K, filed with the Securities and Exchange Commission (“SEC”) on March 4, 2022. In the opinion of management, these interim financial statements present fairly, in all material respects, the Company’s consolidated financial position and results of operations for each of the interim periods presented. Results of operations for interim periods are not necessarily indicative of the results of operations that may be expected for a full year or any future period. Accounting Estimates and Assumptions: The consolidated financial statements are prepared in conformity with GAAP, which require management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reported periods. Actual results could differ significantly from these estimates and assumptions. Material estimates generally susceptible to significant change are related to the determination of the allowance for loan losses, impaired loans, other real estate owned, deferred tax assets, the fair value of financial instruments and other-than-temporary impairment of investment securities. Income Per Common Share: Basic income per share is computed by dividing net income by the weighted-average number of common shares outstanding during the period. Dilutive income per share is computed by dividing net income by the weighted-average number of common shares and potential common shares outstanding. Potential common shares consist of dilutive stock options determined using the treasury stock method and the average market price of common stock. Subsequent Events: Subsequent events are events or transactions that occur after the balance sheet date but before financial statements are issued. Recognized subsequent events are events or transactions that provide additional evidence about conditions that existed at the date of the balance sheet, including the estimates inherent in the process of preparing financial statements. Non-recognized subsequent events are events that provide evidence about conditions that did not exist at the date of the balance sheet but arose after that date. We have reviewed events occurring through the date the financial statements were available to be issued and no subsequent events occurred requiring accrual or disclosure. Recent Accounting Pronouncements: The following is a summary of recent authoritative pronouncements that could impact the accounting, reporting and/or disclosure of financial information by the Company. In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, to change the accounting for credit losses and modify the impairment model for certain debt securities. ASU 2016-13 changes the impairment model for most financial assets to a current expected credit loss (“CECL”) model, replacing the incurred loss model that is currently in use. The new guidance requires an entity to measure all expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions and reasonable supportable forecasts. The CECL model will apply to financial assets measured at amortized cost, such as loans and investments, as well as certain off-balance sheet credit exposures. In May 2019, the FASB issued guidance to provide entities with an option to irrevocably elect the fair value option, applied on an instrument-by-instrument basis for eligible instruments, upon adoption of ASU 2016-13, Measurement of Credit Losses on Financial Instruments. In October 2019, the FASB voted to extend the implementation date for smaller reporting companies, non-SEC public companies, and private companies. This amendment will become effective for the Company on January 1, 2023. In connection with its efforts to implement ASU 2016-13, the Company internally developed and tested a model to apply the provisions of this guidance upon adoption. The Company is currently in the process of evaluating the impact on the consolidated financial statements of adopting ASU 2016-13. The actual impact of adopting ASU 2016-13 will be influenced by the quality, composition, and characteristics of our loan and investment portfolios, as well as the expected economic conditions and forecasts at the time of enactment and future reporting periods. In March 2020, the FASB issued guidance that makes narrow-scope improvements to various aspects of the financial instrument guidance, including the current expected credit losses (CECL) guidance issued in 2016. The amendments related to conforming amendments. For public business entities, the amendments are effective upon issuance of this final ASU. For the amendments related to ASU 2016-13, public business entities that meet the definition of an SEC filer, excluding eligible smaller reporting companies (SRCs) as defined by the SEC, should adopt the amendments in ASU 2016-13 during 2020. Early adoption will continue to be permitted. For entities that have not yet adopted the guidance in ASU 2016-13, the effective dates and the transition requirements for these amendments are the same as the effective date and transition requirements in ASU 2016-13. The Company does not expect these amendments to have a material effect on its consolidated financial statements. In March 2022, the FASB issued ASU 2022-02, Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures, which eliminates the accounting guidance on troubled debt restructurings (TDRs) for creditors in ASC 310-402 and amends the guidance on “vintage disclosures” to require disclosure of current-period gross write-offs by year of origination. The ASU also updates the requirements related to accounting for credit losses under ASC 326 and adds enhanced disclosures for creditors with respect to loan refinancings and restructurings for borrowers experiencing financial difficulty. The amendments in ASU 2022-02 are effective upon the Company’s adoption of ASU 2016-13. In March 2020, the FASB issued guidance to provide temporary optional guidance to ease the potential burden in accounting for reference rate reform. The amendments are effective as of March 12, 2020 through December 31, 2022. The Company does not expect these amendments to have a material effect on its consolidated financial statements. In November 2021, the FASB added a topic to the Accounting Standards Codification, Government Assistance, to require certain annual disclosures about transactions with a government that are accounted for by applying a grant or contribution accounting model by analogy to other accounting guidance. The guidance is effective for financial statements issued for annual periods beginning after December 15, 2021. The amendment became effective January 1, 2022 and did not have a material effect on the consolidated financial statements. Other accounting standards that have been issued or proposed by the FASB or other standards-setting bodies are not expected to have a material impact on our financial position, results of operations or cash flows.
